From what I have gathered, a sufficient amount of ink is necessary to create a conductive trace on paper. When conductive spots emerge, it can be seen that a shell is formed that rises above the actual paper itself. Where as the silver spots soak into the paper and the individual paper fibers can still be seen. This could be due to the fact that the fibers in the paper are wicking away the ink and prohibiting it from coagulating. More tests will be run to try to further saturate the paper with ink and also using transparencies. Transparencies have the benefit of having no fibers that could interfere with the placement of the ink.
